Method and arrangement for on-boarding network service descriptions from various sources in a common service catalogue of NFV orchestration platform

Electronic arrangement (120) for on-boarding services in a common service catalog (106, 406) from a number of source systems (502, 503, 521, 522) of 3rd party service providers in connection with a network function virtualization (NFV) platform in a telecommunication network (110) comprising a mobile network, the arrangement comprising at least one data interface (124) for transferring data, at least one processing unit (122) for processing instructions and other data, and memory (128) for storing the instructions and other data, said at least one processing unit being configured, in accordance with the stored instructions, to cause: creating, in said memory, a service catalog (406) of network services offered by the NFV platform, wherein each cataloged network service is associated with a service description indicative of related transactions that are executable thereon, and responsive to obtaining a network service description (402) from an external source via the data interface, adding at least an indication (408) of the obtained network service description in the catalog, wherein a mapping (410) between a number of original transaction identifiers as provided in the obtained network service description and corresponding harmonized transaction identifiers as being internally commonly adopted and utilized by the platform having regard to the cataloged network services, is established (404, 510) in accordance with a selected conversion logic executed by said at least one processing unit so as to enable management of a target network service incorporating the obtained, on-boarded network service based on the associated harmonized identifiers.
